"I'm diagnosed with body dysmorphia with reading those stupid f*cking tabloids when I was like 13 and feeling like I was ugly, like always," she said in a video for StyleLikeU. "I started starving myself and losing a bunch of weight and I got down to like 95 pounds. When I lost my curves and when my boobs shriveled up into like nothing and I had no shape, it put me in even more of a cage."

Earlier this month, Tallulah's big sister, Rumer Willis, also got candid about constantly being bullied for her looks growing up. "I struggled a lot with my body image," Rumer, 26, wrote in an essay for Glamour magazine. "I wanted to have no butt; I wanted to have no boobs. For a long time I just wanted to look tiny and androgynous. I never really shared what I was going through with my parents, because it was too painful. I didn't know how to ask for help or how to even bring it up."
